What is the standard form for the quadratic function?

f (x) = (x - 3) 2 + 5

f (x) = x² - 6x + 14

Step-by-step explanation:

Standard form is ax² + bx + c = 0 or f (x) = ax² + bx + c

So we are going to expand the equation and combine like terms:

f (x) = (x - 3) ² + 5

f (x) = x² - 3x - 3x + 9 + 5

f (x) = x² - 6x + 9 + 5

f (x) = x² - 6x + 14
